Let Democrats roast in the light of day on this issue.
Their lies won’t stand up to sustained scrutiny.
Controlling the narrative to stay on this issue, benefits Republicans. When Democrats are free to set the narrative, it will be the personal destruction of Trump and Republicans.
Better to fight on favorable terrain. Let the shutdown last through the State of the Union - or until Ruth Bader Ginsburg’s replacement is announced.
At this point I don’t see many (if any) Democrats voting for wall funding in either the house or the senate. So Trump should be doing plan B. Get everything lined up (contracts for wall supplies, military personnel to build the wall, a legal team to defend the president’s right to declare an emergency) before the State of the Union address so once he declares a state of emergency, he can start to build a wall immediately.
